  • Massive drop in sales, need advice
    Anywho, the old mailgun system was able to send emails immediately + had images in them. The recommendations we got were to remove ALL images, and instantly.ai has to delay a few minutes between email. So the emails get out slower and no images, plain text looks a lot more scammy to me and I assume also hurts conversions? Source: 9 months ago
  • Snov or Lemlist
    What about instantly.ai? Any experience around that? Source: 11 months ago
  • Our first email ended up in the user's spam folder
    Yeah, well that's just how it works. You'll need to warm up your domain, there's a lot of ways to do it I would suggest something on the lines of https://instantly.ai/. Source: 11 months ago
  • How I've gotten thousands of customers (over 10 years) through cold outreach while only spending ~$50/month
    There are other tools for this also, like Hunter.io for prospecting and Lemlist or Instantly for sending. Source: 12 months ago

These insights have allowed me to revamp marketing's objectives and set clear goals for the year. I'm looking forward to leveraging what I've learned in past roles to mature the marketing function at Customer.io, better support our customers, and... Source: about 1 year ago
  • Newsletter or phishing?
    Looks like Notion uses customer.io for emails, so probably just a basic marketing/newsletter emails from Notion. Source: about 1 year ago
  • 💰 My Frugal Indie Dev Startup Stack
    The final note I'll make is that I've hand-rolled a few additional features that people are normally paying for. For example, I don't use Mailchimp or any tool like that — I send my marketing mail straight via Sendgrid. I dont use customer.io for my email sequences — even though it's very good — because I was able to just build my own email sequencing system. Time will tell whether I end up needing to replace my... - Source: dev.to / over 1 year ago
